Just wondering if anyone is running a slightly larger profile set of cams in their 4AGE on a standard computer and can give me a no-bullshit take on how it drives?

 

With everything there is always a tolerancebuilt into the std computer, but I'm used to GM products, and mostly carbies, not japanese ECUs and Fuel injection.

 

Ive read just about anything and everything I could find on the net, but its hard to make a judgement without driving one yourself and seeing if it "works" with the STD computer.

 

So enough of the dribble.

 

Anyone running a 16v 4AGE with the STD computer and larger profile cams? Is it bearable for my missus to drive (she CAN drive, not like some females, she deals with the lumpy cam in the torana..) how does traffic go etc etc.

 

Cheers,

Chris

Slightly larger profile? Longer duration or lift? I've driven a bigport on 300 duration cams. It ran on a standard ecu, but wouldn't idle without the spark plug clearances tightened up. From most accounts, anywhere up to 270 duration will run nearly perfectly on a standard ecu.

Longer duration AND more lift.

 

Some say theres was driveable, others say its not, I suppose most of it is personal opinion and how far they have to drive the car/traffic etc.

 

Id like to find someone close to home with some lump in their 4AGE who I can go visit and see how it idles etc for myself, but it seems like thats a bit of hard task.

I have 268 duration with 7.8mm lift in a bigport using stock ECU and it is no problem.

 

Wade cams tell me these cams were developed in conjunction with Toyota to run in MR2's and that this was the largest they could run on the stock ECU.

 

Can't comment on higher lift.
